Not a fix for your question, but I don't see anything wrong with having your copy read "Please refer to Table 7.1 and Table 7.2 for information"
Im following standard English conventions (UK, if you will) and the format at the moment is a wee bit clunky when you have to write something like 'Table 7.1, Table 7.2, Table 7.3, Table 7.4 and Table 7.5.....' as will be the case later in the document. The other arrangment of 'Tables 7.1, 7.2, 7.3, 7.4 and 7.5.....' is much shorter and easier to read - brevity is essential in this document because of limited word count.
Isuspect it would be easier to go the other way, that is to add the "Table" or "Tables" text using Find/Change. As far as I know there is no way to remove part of the text from the paragraph number.
Good suggestion, although I have the para style linked to a 'List of Tables' at the front of the document which shows the complete thing "Table 1.1 School Children in Hong Kong" for example. I thought that Michael Murphy dealt with this in his book, but I am travelling at the moemtn and don't have a copy. I know that Grep can do certain things in the cross reference format window, I'm just unfamiliar with the code!
